How can I add vue-router link as ag-grid-vue column? - vue-router

ag-grid-vue documentation from ag-grid website clearly says:
You can provide Vue Router links within the Grid, but you need to
ensure that you provide a Router to the Grid Component being created.
with sample code:
// create a new VueRouter, or make the "root" Router available
import VueRouter from "vue-router";
const router = new VueRouter();
// pass a valid Router object to the Vue grid components to be used within the grid
components: {
'ag-grid-vue': AgGridVue,
'link-component': {
router,
template: '<router-link to="/master-detail">Jump to Master/Detail</router-link>'
}
},
// You can now use Vue Router links within you Vue Components within the Grid
{
headerName: "Link Example",
cellRendererFramework: 'link-component',
width: 200
}
What's missing here is how to make the "root" Router available. I've been looking into various sources and see many people have the same problem, but none got a clear answer.
https://github.com/ag-grid/ag-grid-vue/issues/1
https://github.com/ag-grid/ag-grid-vue/issues/23
https://github.com/ag-grid/ag-grid-vue-example/issues/3
https://forum.vuejs.org/t/vue-cant-find-a-simple-inline-component-in-ag-grid-vue/21788/10
Does ag-grid-vue still work with vue-router, then how, or is this just outdated documentation? Some people claim it worked for them so I assume it worked at one point.
I am not looking for cool answer at this point. I just want to know if it is possible. I tried passing router using window or created() and none worked so far.
Thank you!

the approach suggested by #thirtydot works well. The only downside was the user cannot right-click, but I found you can just define href link. So when you left-click, event listener makes use of router. When you right-click and open in new tab, browser takes href link.
You still need to make your root router available. Below code sample assumes you have the code inside the vue-router-aware Vue component that consumes ag-grid, hence this.$router points to the root router.
{
headerName: 'ID',
field: 'id',
cellRenderer: (params) => {
const route = {
name: "route-name",
params: { id: params.value }
};
const link = document.createElement("a");
link.href = this.$router.resolve(route).href;
link.innerText = params.value;
link.addEventListener("click", e => {
e.preventDefault();
this.$router.push(route);
});
return link;
}
}

How do I properly import multiple components dynamically and use them in Nuxt?

I need to implement dynamic pages in a Nuxt + CMS bundle.
I send the URL to the server and if such a page exists I receive the data.
The data contains a list of components that I need to use, the number of components can be different.
I need to dynamically import these components and use them on the page.
I don't fully understand how I can properly import these components and use them.
I know that I can use the global registration of components, but in this case I am interested in dynamic imports.
Here is a demo that describes the approximate logic of my application.
https://codesandbox.io/s/dank-water-zvwmu?file=%2Fpages%2F_.vue
Here is a github issue that may be useful for you: https://github.com/nuxt/components/issues/227#issuecomment-902013353
I've used something like this before
<nuxt-dynamic :name="icon"></nuxt-dynamic>
to load dynamic SVG depending of the icon prop thanks to dynamic.
Since now, it is baked-in you should be able to do
<component :is="componentId" />
but it looks like it is costly in terms of performance.
This is of course based on Nuxt components and auto-importing them.
Also, if you want to import those from anywhere you wish, you can follow my answer here.
I used this solution. I get all the necessary data in the asyncData hook and then import the components in the created () hook
https://codesandbox.io/s/codesandbox-nuxt-uidc7?file=/pages/index.vue
asyncData({ route, redirect }) {
const dataFromServer = [
{
path: "/about",
componentName: 'myComponent'
},
];
const componentData = dataFromServer.find(
(data) => data.path === route.path
);
return { componentData };
},
data() {
return {
selectedRouteData: null,
componentData: {},
importedComponents: []
};
},
created() {
this.importComponent();
},
methods: {
async importComponent() {
const comp = await import(`~/folder/${this.componentData.componentName}.vue`);
this.importedComponents.push(comp.default);
}

Error in rendering vue.js file using view instance new Vue()

I am working with vue.js, while rendering vue page i am getting below
error "Cannot GET /KForm"
Below are my code in main.js
import * as componentBase from "#app/app_start"
import Form from "#views/Form/Form.vue"
import KForm from "#views/KForm/KForm"
const NotFound = { template: '<p>Page not found</p>' }
const routes = {
'/': Form,
'/recap': Recap,
'/KForm': KForm
}
const app = new Vue({
...componentBase,
data: {
currentRoute: window.location.pathname
},
computed: {
ViewComponent() {
return routes[this.currentRoute] || NotFound
}
},
render: h => h(this.ViewComponent)
}).$mount("#app")
I'm not sure what your webpack config is, but shouldn't the KForm import be this:
import KForm from "#views/KForm/KForm.vue"
^^^^
currentRoute is set to window.location.pathname one time only when the component is instantiated. When you click a link (or navigate directly from the browser's address bar) to, say /KForm, the window location changes and the browser tries to fetch the webpage at that new address just like in a traditional non-SPA webpage. This will fail unless the server responds to that URL.
To prevent the browser from doing this, you'll have to intercept <a> clicks and use the history API to change the window location without reloading the page, then change currentRoute accordingly.
Or better yet, just use vue-router which does all this for you. See this for example server configurations for HTML5 history mode.

Vue router not navigating

I'm having problems getting VueRouter to navigate.
Within my app some pages work fine, and with identical code, other pages the routing doesn't work / page doesn't update navigate.
Are there some gotchas with the router? Like you cannot call the router from within components or... ?
named route in my app
export default new VueRouter({
routes: [
{
path: '/grams/one/:cname',
component: GramsOne,
name: "gramsOne"
},
...
Then inside a component on a page:
<q-btn v-for='(rel, key) in gram.relatedItems' :key='key'
color='secondary'
#click="goGram(rel)"
>
{{rel.cn}}
</q-btn>
// later in the script:
methods: {
goGram(gram) {
let newRoute = {
name: 'gramsOne',
params: {cname: gram.cname}
}
console.log('goGram', newRoute)
this.$router.push(newRoute)
}
},
Elsewhere on the same page, simple routes work.
The URL address will get updated in the browser.
I see the right console log with route info
But the page/content will not change.
Once the URL bar has been updated, I can hit ctrl-R and the new page will get loaded. So the destination route is working fine.
From other pages in the same app I can use the same route to target new destination and loads fine.
This is also loading with the same URL and just a query param different that is causing the problem.
/app/items/foo
/app/items/bar
where bar is a type of some property /app/items/:foo
I have tried various combinations of named routes, routes using etc, and can't really see a pattern.
"vue": "~2.5.0",
"vue-resource": "^1.3.4",
"vue-router": "^2.7.0"
Thanks any hints!
The Component in this case is the same, so vue will reuse the instance.
The this.$route in the component will change but created(), beforeMounted() and mounted() hooks won't be callled.
Which is probably where you use the this.$route.params.cname
To force vue to create a new component instance you can set a unique key on the like <router-view :key="$route.fullPath">
Another options is to react to changes in the $route with a watcher:
watch: {
"$route.params.cname": {
handler(cname) {
// do stuff
},
immediate: true
}
}
Router can be called within a component just fine. In fact, you usually call router from the component.
From the code snippets provided, at one point in the code you use cn, then at other point you use cname. That might be the problem why it never quite work for you.
I create a codesandbox to recreate your scenario, and besides that minor naming mentioned above, things seem to work just fine.

Vue-multiselect inconsistent reactive options

So I'm building an application using Laravel Spark, and therefore taking the opportunity to learn some Vue.js while I'm at it.
It's taken longer for me to get my head around it than I would have liked but I have nearly got Vue-multiselect working for a group of options, the selected options of which are retrieved via a get request and then updated.
The way in which I've got this far may well be far from the best, so bear with me, but it only seems to load the selected options ~60% of the time. To be clear - there are never any warnings/errors logged in the console, and if I check the network tab the requests to get the Tutor's instruments are always successfully returning the same result...
I've declared a global array ready:
var vm = new Vue({
data: {
tutorinstruments: []
}
});
My main component then makes the request and updates the variable:
getTutor() {
this.$http.get('/get/tutor')
.then(response => {
this.tutor = response.data;
this.updateTutor();
});
},
updateTutor() {
this.updateTutorProfileForm.profile = this.tutor.profile;
vm.tutorinstruments = this.tutor.instruments;
},
My custom multiselect from Vue-multiselect then fetches all available instruments and updates the available instruments, and those that are selected:
getInstruments() {
this.$http.get('/get/instruments')
.then(response => {
this.instruments = response.data;
this.updateInstruments();
});
},
updateInstruments() {
this.options = this.instruments;
this.selected = vm.tutorinstruments;
},
The available options are always there.
Here's a YouTube link to how it looks if you refresh the page over and over
I'm open to any suggestions and welcome some help please!
Your global array var vm = new Vue({...}) is a separate Vue instance, which lives outside your main Vue instance that handles the user interface.
This is the reason you are using both this and vm in your components. In your methods, this points to the Vue instance that handles the user interface, while vm points to your global array that you initialized outside the Vue instance.
Please check this guide page once more: https://v2.vuejs.org/v2/guide/instance.html
If you look at the lifecycle diagram that initializes all the Vue features, you will notice that it mentions Vue instance in a lot of places. These features (reactivity, data binding, etc.) are designed to operate within a Vue instance, and not across multiple instances. It may work once in a while when the timing is right, but not guaranteed to work.
To resolve this issue, you can redesign your app to have a single Vue instance to handle the user interface and also data.
Ideally I would expect your tutorinstruments to be loaded in a code that initializes your app (using mounted hook in the root component), and get stored in a Vuex state. Once you have the data in your Vuex state, it can be accessed by all the components.
Vuex ref: https://vuex.vuejs.org/en/intro.html
Hope it helps! I understand I haven't given you a direct solution to your question. Maybe we can wait for a more direct answer if you are not able to restructure your app into a single Vue instance.
What Mani wrote is 100% correct, the reason I'm going to chime in is because I just got done building a very large scale project with PHP and Vue and I feel like I'm in a good position to give you some advice / things I learned in the process of building out a PHP (server side) website but adding in Vue (client side) to the mix for the front end templating.
This may be a bit larger than the scope of your multiselect question, but I'll give you a solid start on that as well.
First you need to decide which one of them is going to be doing the routing (when users come to a page who is handling the traffic) in your web app because that will determine the way you want to go about using Vue. Let's say for the sake of discussion you decide to authenticate (if you have logins) with PHP but your going to handle the routing with Vue on the front end. In this instance your going to want to for sure have one main Vue instance and more or less set up something similar to this example from Vue Router pretending that the HTML file is your PHP index.php in the web root, this should end up being the only .php file you need as far as templating goes and I had it handle all of the header meta and footer copyright stuff, in the body you basically just want one div with the ID app.
Then you just use the vue router and the routes to load in your vue components (one for each page or category of page works easily) for all your pages. Bonus points if you look up and figure using a dynamic component in your main app.vue to lazy load in the page component based on the route so your bundle stays small.
*hint you also need a polyfill with babel to do this
template
<Component :is="dynamicComponent"/>
script
components: {
Account: () => import('./Account/Account.vue'),
FourOhFour: () => import('../FourOhFour.vue')
},
computed: {
dynamicComponent() {
return this.$route.name;
}
},
Now that we are here we can deal with your multiselect issue (this also basically will help you to understand an easy way to load any component for Vue you find online into your site). In one of your page components you load when someone visits a route lets say /tutor (also I went and passed my authentication information from PHP into my routes by localizing it then using props, meta fields, and router guards, its all in that documention so I'll leave that to you if you want to explore) on tutor.vue we will call that your page component is where you want to call in multiselect. Also at this point we are still connected to our main Vue instance so if you want to reference it or your router from tutor.vue you can just use the Vue API for almost anything subbing out Vue or vm for this. But the neat thing is in your main JS file / modules you add to it outside Vue you can still use the API to reference your main Vue instance with Vue after you have loaded the main instance and do whatever you want just like you were inside a component more or less.
This is the way I would handle adding in external components from this point, wrapping them in another component you control and making them a child of your page component. Here is a very simple example with multiselect pretend the parent is tutor.vue.
Also I have a global event bus running, thought you might like the idea
https://alligator.io/vuejs/global-event-bus/
tutor.vue
<template>
<div
id="user-profile"
class="account-content container m-top m-bottom"
>
<select-input
:saved-value="musicPreviouslySelected"
:options="musicTypeOptions"
:placeholder="'Choose an your music thing...'"
#selected="musicThingChanged($event)"
/>
</div>
</template>
<script>
import SelectInput from './SelectInput';
import EventBus from './lib/eventBus';
export default {
components: {
SelectInput
},
data() {
return {
profileLoading: true,
isFullPage: false,
isModalActive: false,
slackId: null,
isActive: false,
isAdmin: false,
rep: {
id: null,
status: '',
started: '',
email: '',
first_name: '',
},
musicTypeOptions: []
};
},
created() {
if (org.admin) {
this.isAdmin = true;
}
this.rep.id = parseInt(this.$route.params.id);
this.fetchData();
},
mounted() {
EventBus.$on('profile-changed', () => {
// Do something because something happened somewhere else client side.
});
},
methods: {
fetchData() {
// use axios or whatever to fetch some data from the server and PHP to
// load into the page component so say we are getting the musicTypeOptions
// which will be in our selectbox.
},
musicThingChanged(event) {
// We have our new selection "event" from multiselect so do something
}
}
};
</script>
this is our child Multiselect wrapper SelectInput.vue
<template>
<multiselect
v-model="value"
:options="options"
:placeholder="placeholder"
label="label"
track-by="value"
#input="inputChanged" />
</template>
<script>
import Multiselect from 'vue-multiselect';
export default {
components: { Multiselect },
props: {
options: {
type: [Array],
default() {
return [];
}
},
savedValue: {
type: [Array],
default() {
return [];
}
},
placeholder: {
type: [String],
default: 'Select Option...'
}
},
data() {
return {
value: null
};
},
mounted() {
this.value = this.savedValue;
},
methods: {
inputChanged(selected) {
this.$emit('selected', selected.value);
}
}
};
</script>
<style scoped>
#import '../../../../../node_modules/vue-multiselect/dist/vue-multiselect.min.css';
</style>
Now you can insure you are manging the lifecycle of your page and what data you have when, you can wait until you get musicTypeOptions before it will be passed to SelectInput component which will in turn set up Multiselect or any other component and then handle passing the data back via this.$emit('hihiwhatever') which gets picked up by #hihiwhatever on the component in the template which calls back to a function and now you are on your way to do whatever with the new selection and pass different data to SelectInput and MultiSelect will stay in sync always.
Now for my last advice, from experience. Resist the temptation because you read about it 650 times a day and it seems like the right thing to do and use Vuex in a setup like this. You have PHP and a database already, use it just like Vuex would be used if you were making is in Node.js, which you are not you have a perfectly awesome PHP server side storage, trying to manage data in Vuex on the front end, while also having data managed by PHP and database server side is going to end in disaster as soon as you start having multiple users logged in messing with the Vuex data, which came from PHP server side you will not be able to keep a single point of truth. If you don't have a server side DB yes Vuex it up, but save yourself a headache and wait to try it until you are using Node.js 100%.
If you want to manage some data client side longer than the lifecycle of a page view use something like https://github.com/gruns/ImmortalDB it has served me very well.
Sorry this turned into a blog post haha, but I hope it helps someone save themselves a few weeks.

Vuejs - require is not defined

I am just playing around with vuejs router and try to load a component.
I used the sample code and changed foo
// Define some components
var Foo = Vue.extend({
template: require('./components/test.vue')
});
var Bar = Vue.extend({
template: '<p>This is bar!</p>'
});
// The router needs a root component to render.
// For demo purposes, we will just use an empty one
// because we are using the HTML as the app template.
var App = Vue.extend({})
// Create a router instance.
// You can pass in additional options here, but let's
// keep it simple for now.
var router = new VueRouter()
// Define some routes.
// Each route should map to a component. The "component" can
// either be an actual component constructor created via
// Vue.extend(), or just a component options object.
// We'll talk about nested routes later.
router.map({
'/foo': {
component: Foo
},
'/bar': {
component: Bar
}
})
// Now we can start the app!
// The router will create an instance of App and mount to
// the element matching the selector #app.
router.start(App, '#app')
I also tested it with
Vue.component('Foo', {
template: require('./components/test.vue')
})
In my test.vue i have
<template>
<h2>Test</h2>
</template>
But not as soon as i use require i get everytime the error Required is not defined in my dev tools.
What do i wrong here?
require is a builtin in the NodeJS environment and used in Grunt build environments.
If you also want to use it in a browser environment you can integrate this version of it: http://requirejs.org

Use Browserify or Webpack as there is active support in the Vue community
